France, October 1950, This study briefly 

 traces the growth of the French canned fish 

 industry and considers, in some detail, methods 

 for the preparation and canning of fish. The 

 study is in tvro sections: fish of small or 

 average-body length (sardines, herring, and 

 mackerel), and tnose species of larger propor- 

 tions (tuna). Methods now in practice are ex- 

 plained for preparing the small fish, includ- 

 ing trimming, cleaning, and curing; drying and 

 cooking; and various apparatus used in cooking 

 and/or drying the fish. Various methods for 

 cooking or drying the fish are considered in 

 scans detail— desp-f at fryers, cooking in brine, 

 steam cooking, hot-air ovens, and the recently- 

 developed ovens for cooking with infrared rays . 

 As to the nature of the infrared-ray ovens, two 

 types are now in use; one functioning on gas 

 and the other on electricity. A detailed de- 

 scription of the ovens and their results are 

 given in this booklet. The processing of fish 

 after they have been placed in cans is largely 

 accomplished by two systems, that of the Mather 

 and Piatt system and the International Machinery 

 Corporation system, and a detailed description 

 is given for operations of these conveyor-type 

 cookers. Tuna are canned by these two methods: 

 packing tuna in the cans after cooking or pack- 

 ing tuna into cans prior to cooking. The latter 

 method is used principally for the canning of 

 natural tuna "thon au natural." Under a con- 

 sideration of general techniques, the publica- 

 tion considers the use of infrared rays during 

 the precooking process, the employment of elec- 

 trostatic heating, and the use of antibiotics 

 in the sterilization process. 



Fisheries Investi/^tions of the St. Johns River and 

 Lake Okeechobee , 1943-50, with Rec onmendations 

 for Managgnent (A Report to the director and Mem- 

 bers of the Florida Game and Fresh Water Fish 

 Commission, Revised), 48 p., tables, processed. 

 Fish Management Division, Florida Game and Fresh 

 Water Commission, Tallahassee, Florida, April 3, 

 1951. In this publication, factual Information 

 is presented on the life history, abundance, and 

 growth of the important species of fresh-water 

 fish in the St. Johns River and Lake Okeechobee 

 area. The results of a survey show that bream, 

 crappis, and catfish can be marketed commerci- 

 ally with an annual canbined VELLue of |1.2 mil- 

 lion. The findings of the two-year survey in- 

 clude information on the physiography of the 

 fresh-water areas, the effect of various ccm- 

 mercial fishing operations upon the game fish 

 populations, potential annual production and 

 economic potential of fishery resources, aid to 

 the economic status of the communities involved 

 during the course of the survey, and the methods 

 of improving sport fishing. This publication 

 makes extensive use of graphs and charts to il- 

 lustrate the findings of the survey, and recom- 

 mendations are made in the conclusion for these 

 Florida fresh-water areas. 



Handbook of Emergency Defense Activities . II9 p. , 

 ■printed, 25 cents. GeneraQ. Services Adminis- 

 tration, Washington, D.C. (For sale by Super- 

 intendent of Documents, Washington 25, D.C.), 

 June 1951. This is a guide to Federal agencies 

 all or part of whose functions are devoted to 

 mobilization or to other related phases of the 

 defense program. No attempt has been made to 

 include activities of agencies originally cre- 

 ated for nondefense purposes, unless separate 

 organization entities have been established to 

 handle emergency functions. Included are brief 

 organizational outlines and the names and ad- 

 dresses of officials of emergency defense agen- 

 cies, the Department of Defense, and the United 

 States Coast Guard. Included is the Defense 

 Fisheries Atininistration. This booklet is de- 

 signed to assist the public in reaching the 

 services it needs in connection with the de- 

 fense program. 



"Improving the Design of Fishing Boats," by Jan- 

 Olof Traung, article, FAO Fisheries Bulletin . 

 Jan. /Feb .-Mar ./Apr. 1951, vol. 4, no. 1-2, 

 pp. 3-27, illus., printed. Food and Agricul- 

 ture Organization, Rome, Italy. (Bulletin 

 available from International Documents Service, 

 Columbia University Press, 2960 Broadway, New 

 York 27, N. Y., annual subscription US|1.50, 

 single copy 30 cents.) This article attempts 

 to show that it is of the utmost importance to 

 the fishery industries that fishing boats be 

 designed so that they will perform as econo- 

 mically and efficiently as possible. Ccmpared 

 with other sections of the industry, however, 

 little research, study, and governnental sup- 

 port have been given to the design of fishing 

 boats. This article gives some examples as to 

 how designs can be ingiroved with great savings 

 in operation p"fi better performance of the 

 boats. The author points out that FAO is keep- 

 ing abreast of the developments In fishing 

 boat design and building and is willing to 

 discuss and exchange information with indivi- 

 dual fishing boat designers. In addition, FAO 

 Is willing to study designs submitted by mem- 

 ber governnBnts to suggest Iniprovements, and 

 to advise on further research, tank testing, 

 etc, , in order to avoid duplication of work. 

 On account of the large expenses of making 

 tests and research by any one owner or build- 

 er, the author suggests that regional fisher- 

 ies associations, etc. , cooperate in conduct- 

 ing test programs where boat shapes and re- 

 quirements are similar, spreading the cost so 

 as not to place too large a burden on any one 

 operator. This article includes general re- 

 marks on fishing boat design; speed; a sum- 

 mary of fishing boat model tests; and a dis- 

 cussion of tank-testing experiments and their 

 results.
